A new N-2,3,4-trifluorophenyl-3,5-di-tert-butylsalicylaldimine (1) complexes with Cu(II) (2) and Pd(II) (3) have been synthesized and characterized by X-ray crystallography, UV–Vis, IR, 1H NMR and EPR spectroscopic techniques. The X-ray crystal structure of complex 2 reveals tetrahedrally distorted square-planar coordination geometry around Cu(II). The UV/Vis and EPR results indicate that the solid state geometry of 2 remains unchanged in solutions. Chemical oxidation of 3 with Ce(IV) in CHCl3 generates relatively stable Pd(II)–phenoxyl radical complex (g = 2.0073). The results related with the chemical oxidation of 2 and 3 as well as the catalytic activity of 3 in the hydrogenation of PhNO2 are presented.
The synthesis, structural, spectroscopic characterization and reactivity of a novel N-2,3,4-trifluorophenyl-3,5-di-tert-butylsalicylaldimine and its complexes with Cu(II) (2) and Pd(II) (3), have been described. The X-ray structure analyses for 2, reveal that weak C(sp2)–H⋯F, π–π stacking and C(sp3)–H⋯π interactions are responsible for lattice stabilization.Figure optionsDownload as PowerPoint slide
